SPECIFICATION forming part Of Letters Patent N0. 594,822, dated November 30, 1897.

Application filed February 27, 1897- Serial No. 625,333. (No model.)

My invention relates to an improvement in window-sashes, and is particularly designed for use in railway-cars, the object being to provide a window-sash adapted to be moved in the window-frame in the usual manner, and also adapted to be swung outwardly at either side, so as to constitute a guard against the admission of smoke, cinders, and other flying particles, as well as to provide an opening for the ventilation of the car. I

With these ends in view my invention con- ,sists in certain novel features of construction and combinations of parts, as will be hereinafter more fully described, and pointed out in the claims. 1

In the accompanying drawings, Figure 1 represents a view of my improvement, the inner section of the sash being shown in its closed position, the bolt throwing device, lock, and easing being removed from one of the supplemental rails. Fig. 2 is a horizontal sectional View of the same, with the inner section of the sash in an open position. 'Fi gs. 3, 4, and 5 are detached views of parts of my improvement, and Fig. 6 is a view-in plan of the inner section of the sash. I

A represents a window-frame provided with the usual grooves, within which is adapted to slide the outer section 1 of the windowsash. This section 1 is provided on its inner face with a continuous flange 2, the purpose of which will be hereinafter explained. Frame A is also provided with an upper sash 3, which latter, in the present instance, is permanently secured to said frame. However, if desired, it may be removably held therein, or it may be adapted to slide within said frame, or it may be dispensed with altogether.

B is the inner section of the window-sash, which is provided with the usual pane of glass e. To the side rails 5 5 of section B are pivot-ally connected the supplemental side rails or strips 6 6, the connection being effected by means of the strap-hinges 7' 7 7 7, which latter are preferably located as shown in .Fig. 6 of the drawings. In order to provide against the admission of air between the hinged parts, I have constructed the supplemental rails or strips 6 6 with curved grooves 8 8 and the side rails 5 5 with curved side edges 9 9, which latter snugly fit within the former and constitute practically an airtight joint between said parts, but permitting free movement of the parts without opening up any joint. The entire outer edges of the top, bottom, and supplemental rails or strips are L-shaped and constitute an unbroken flange 10, which latter, when section B and its hinged connections are in their normal or closed position, registers with and overlaps the flange 2, formed on section 1, thus forming a tight joint whereby the entrance of air and dust is prevented.

Secured to the supplemental rails or strips 6 6 of sash-section B .are the bolt-guides 1-1, which latter are located at the respective ends of said supplemental rails or strips and are designed to support and guide the ends of locking-bolts 12. These bolts are moved simultaneously in either direction to engage or disengagethe bolt-keepers 13, carried by the outer sash-section 1 by means of the boltthrowing devices 14. Each of these boltthrowing devices consists of a plate 15, provided with alocking-disk l6, apivoted thumbpiece 17, and an inwardly-projecting post or stem 18, which latter projects through the casing 19 and has secured thereon the toothed wheel 20. When these bolt-throwing devices are in their operative position, the ends of stems or posts 18 rest in the sockets 21, located in the front faces of the supplemental rails or strips 6 6, while the wheels 20 mesh with the toothed or rack-bar sections of bolts 12,

and hence it will be apparent that when the 5 bolt-throwing devices are rotated to the right the upper and lower bolts are moved simultaneously toward each other and their ends moved out of locking contact with the keepers carried by the outer sash-section 1, thus rendering it possible to entirely remove sectionB from section 1. Such removal, however, is only necessary when it is desired to make repairs.

In order to prevent the removal above referredto being made by unauthorized persons, I have secured to each casing 19 a lock 22, the bolt of which, when in its locked position, being adapted to rest within the recess Ell, formed in the locking-disk 16 of the bolt-throwin g device, whereby rotation of the latter is prevented.

One of the great advantages of my improvement over the devices heretofore patented is in its simplicity of construction wherein it is made possible for all travelers on cars, whether skilled or not, to take in its operation at a glance, so as to enable them to open and close the window without calling to their assistance any of the train attendants.

\Vhen a train has been made up of a series of cars equipped with my improved windows, the brakeman should unlock all the locks farthest removed from the engine or front of the train, the locks located on the supplemental rails or strips nearest the front of the train being maintained in their locked position, so that when a passenger wishes to swing the sash outwardly the locked side thereof will constitute the pivotal point on which the window will swing, the outward movement of said window being regulated by the stop 25, secured to the adjacent faces of section B and bottom sash-rail of section 1, respectively. This outward throw of the window is accomplished by simply grasping thumbpieee 17 and turning it to the right, which operation causes gear or wheel 20, by reason of its engagement with the rack-bar sections of bolts 12, to draw the latter inwardly, thus releasing the bolts from engagement with the keepers 13, carried by the outer section 1 of the window-sash, and permitting the inner section B of the sash to be forced outwardly, as shown in Fig. 2 of the drawings, the opening or space thus formed being sufficient for the purpose of ventilation, and

Y the angle of inclination assumed by section B acts as a guard and prevents the admission into the car. of cinders, smoke, and other flyin g objects.

The stop 25 is composed of two sections pivoted together at one end and adapted when the window is closed to rest one on the other.

The. window may be closed when desired by simply taking thumb-piece 17 and pulling thereon inwardly, and after the inner and outer sections of the window have alined they may be locked together by turning the thumbpiece to the left,whieh operation causes wheel 20 to engage the teeth of the rack-bar sections of bolts 12 and simultaneously force the latter within the keepers 13, where the two sections 1 and B are firmly locked together.

Should it become necessary during a trip to change the position of the engine from front to rear, the locks previously unlocked should be locked and the ones located on the opposite sides of the window unlocked, after which the windows may be opened or closed, as before described.

By always keeping one of the locks locked it will be impossible for any one other than the custodian of the key to remove theinner section from its normal or operative position.

The front face of the lower rail of outer section 1 is provided with the usual lift 26, by means of which the entire sash may be raised or lowered in the ordinary manner. Any of the well-kn own means may be employed for holding said window elevated when used in the manner above stated.

In order to provide for a tight and neat joint at the juncture of the two sections 1 and B of the window and further to insure alinement of the inner and outer side faces of the rails constituting said sections, I have constructed the ends of bolts 12 wedge-shaped, and hence it will be apparent that as soon as said ends are moved to engage the keepers 13 the tendency will be to gradually draw section B inwardly until the bolts have been moved to their limit and the sections alined. It is evident that changes in the construction and relative arrangement of the several parts might be made without avoiding my invention, and hence I would have it understood that I do not restrict myself to the particular construction and arrangement of parts shown and described; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A window-sash, comprising an outer and an inner section, the sides of the latter carrying strips pivoted thereto and means for locking either or both of said pivoted strips to the outer section.

2. A window-sash, comprising an outer and an inner section, the sides of the latter carrying strips pivoted thereto, the meeting edges of said strips and inner section constructed to overlap, and means for locking either or both of said pivoted strips to the outer section.

3. A window-sash, comprising an outer and an inner section, the sides of the latter carrying strips pivoted thereto, means for locking either or both of said pivoted strips to the outer section and means for limiting the out ward movement of the inner section.

4. A window-sash, comprising an outer and an inner section, the sides of the latter carrying strips pivoted thereto, devices for connecting either or both of said pivoted strips to the outer section and means for locking said connecting devices against movement.

5. In a window-sash, the combination with an outer and an inner section, and supplemental strips or rails carried by and pivotally connected to the side rails of the inner section, of locking-bolts carried by said pivoted strips for locking either or both of the ICC pivotal strips to the outer section and means for actuating said bolts, substantially as set forth.

6. In a Window-sash, the combination with an outer and an inner section, and supplemental strips or side rails carried by and pivotally connected to the side rails of the inner section, of locking-bolts carried by said pivoted strips for locking either or both of the pivotal strips to the outer section, means for actuating said bolts and locks adjacent to said actuating mechanism whereby either or both of said mechanisms may be locked against unauthorized manipulation, substantially as set forth.

7. In a window-sash, the combination with outer and inner sections, and supplemental strips or side rails carried by and pivotally connected to the side rails of the inner sec-- tion, of locking-bolts carried by said pivoted strips and provided with toothed ends resting opposite one another and held in position by a casing, and bolt-throwing devices each provided with a toothed wheel for engaging the toothed sections of its respective bolts, whereby either or both of the pivotal strips may be locked to and unlocked from the outer section, substantially as set forth.

8. In a window-sash, the combination with a window-frame, and a window-sash consist ing of an outer and an inner section, the former being adapted to slide within said window-fram e, while the latter section is provided with pivoted side strips carried thereby, of locking-bolts carried by said pivoted strips for locking either or both of the pivotal strips to the outer section and means for throwing and releasing said bolts, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses. JAMES M. BOLTON.
